What is the market price of Daphne odora?

The plant "Aquilaria sinensis" is not expensive in itself, but once it is infected by a special mold (parasitic phimosis), it will be forced to secrete a dark aromatic resin-after several years, this resin is slowly embedded in the wood center-forming an expensive "Daphne". Daphne is one of the most expensive raw materials in the world and can be used as medicine or perfume. The price per kilogram of "first-class Daphne odora" can reach $6,543,800+(RMB690,000). Is it sweet? Where to? Dear, please refer to it.
